fo all whom Lt may concern:

" Be it known that I, Jolla* B. BARTHOL- Mew, a citizen of theUnitedStates, residing at Peoria, inthe county of Peoria and State 5 ofIllinois, have invented certain new and` useful Improvements in'Automobiles, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to running gears for motor vehicles and has forits object the provision of suoli a running gear comprising a main orbody frame and an engine or motor frame, the two so related andconnected l5 as to obviate numerous ditlieulties that have beenencountered in motor vehicle constructions.

In the accompanying drawings which illustrate a practical embodiment ofmy in- 2o`weptioi1-Fignre 1 is a side view of the runenlarged viewsshowing details of the running gear.

In the drawings the running gear of the vehicle is shown as providedwith the front wheels 1, 1, and the rear wheels 2, 2, the

former carried by the front axle 3, to which they are connected bysteering knuckles, and the latter connected to the divided rear axle Theaxles are held parallel to each other,

and more or less rigidly by means of the get r frame which comprises theside bars 6, T, the front elliptic springs 8, S, interposed between theframe bars, and the front axle. and springs 9, 9, interposed between itthe rear ends the springs 9 are suspended in swinging links 15, whichare pivotally connected at 15n to upwardly turned arms 15b, in turnconnected to the rear aXlc fl, 5,.and prefer- '45 ably provided byextending one of the leaves of each of two supplemental springs 1G, 16,to be described.

At the front ends the elliptic springs 8. S, are connected to the sidebars C, 7, by means of clamp ,plates 18, 1S, and at the bottom thesesprings are connected to the front axle by fastening clips or brackets17.

Wit-hin the wheel frame above referred to, there is arranged an engineframe, having side parts 19, 19, across connected parts 20. The'rearends o f the side parts 19, 19, are joined to the springs 16, 16, whichextend backward, and have their rear ends situated under the rear axlehousing 4, 5, being flexibly or pivotally connected thereto by means ofa friction gripping clamp as .12, having a depending ear or plate ,23,to which at 22, is pivoted the lug 21,' of the fastening device at therear end of the spring 16. The clamp 12 is held irmly to the axlehousing by means of a bolt lt,

which draws together the two ears or projeetions 13 of the clamp. Thispart of the frame work is stayed by means of the link devices at 10, 10,pivotally connected at their upper ends to the side part 19, 19, of theengine frame, and pivotally connected at 11 to the axle clamp, the headsof the bolts les, being preferably formed with ears .to receive thepivots. These bracing or staying devices are adjustable, there being twoparts, 1()a and 10b of each link, and the adja- Y cent parts beingoppositely threaded, and provided with a correspondingly threadednut-like connectingr device 10F. By adjust# ing this nut 10c-fthe rearaxle may be moved backward or forward to vary vthe tension on thedriving chain, such movement of the.

axle being tion at 22.

The engine frame having the parts just described is connected to thewheel frame, or frame, by means of a longitudinal hinge at fjoining'this frame to a cross bar, or bars, at 2li, carried by the Wheel frame.It is also connected to the latter :traine by means of stay rods 26, 26,which at their forward ends are connected to the permitted by thepivotal connecclamps 27, secured to the front axle, 3, and' .attheirrear endspivoted as at 528, 28, to the Yfront cross part 20 of theengine frame.

The side parts 19, and the cross parts of the engine frame, I prefer tomake in the way shown, that is to say, with bentbars of strap metal at29, 30, spaced and braced by blocks 31, the latter also furnishingsupports for a number of the parts that have to be I secured to thisframe. 32 is a supplemental cross bar on the engine frame which supportsthe rear part of the engine and certain auxlliary parts.

' the two frames in relation to each other;

' placement of the various parts of the engine that is to say, that thewheel frame, or body frame, can be subjected to lateral torsion andtwisting to a-considerable extent, without al'l'ecting the position ofthe engine frame, and the parts supported thereby, and vice versa,v thelatter can have shxoclrs and jars imparted to itwithout their beingtransmitted to the body frame or the wheel frame.

It is well known that a large part of the power of the engine invehicles of this class is 'Wasted because of its being expended upon thebody springs, and because of the disat each rise and fall ofl any of thewheels, such as are frequently experienced even in traveling on ordinaryroads. Even the lateral tilting of the ily-wheels when rapidly rotatingis a serious impediment to the proper action of the parts. In thepresent case, one or more of the wheels can suddenly drop below, or riseabove, the normal level of the bottom points of the wheel peripheries,without affecting the proper movement of the engine. 1n this connection,it is noted that the links. 26, 26, while acting effectively as' lstrutsbetween the front axle andengine frame, do not interfere with thetorsion of the running gear frame or body frame in relation to theengine frame. Another cause of discomfort and inconvenience in the useof such vehicles of this class, is the constant throbbing, or pounding,that is transmitted from the crank shaft to the body frame and the wheelframe, this being especially true where the engine parts and set offrame parts and springs largely indel pendent of those which'carry theweight of the body. l

', 5l'iould lthe two frontwheels, or thel two rear wheels, or all four,suddenly rise orv fall, the inertia effect of the heavy parts of theengine and power transmitting devices is largely overcome, the latterbeing allowed.

fto retain their positionsv as to horizontal.

these tofthe rear axle. frame and the running gear frame should planesuntil the running gear and body frame are restored to their proper posi-,.tirins, because of the independence of the frames a'd the peculiarmeans of connecting In ease the engme thus be vertically moved relativeto each other, the links 15 and the hinges 22 allow great freedom. 'hensuch relative movement is occurring the link connections at l0 ,acteither as struts or ties, according as the rear axle is rising orfalling, and tend to rock the axle housing '42, 5, bodily and this ispermitted by the hinged parts at 2l, 23, which'also accommodate thebackward and forward movements of the rear ends of the springs 16.During such movements of the partsthe linlsl prevent the transfer to thebody frame of shocks or strains.
